Sell the 350 & three speed Turbo 400. Get an AMC 360 block and stuff it with AMC 401 crank & rods. 385 Cu.In. AMC with thicker cylinder walls. Run Indy Heads & a Torquey Roller Camshaft. Create a desireable Classic American Motors Gremlin with ReSale Value and Collectible Interest. I would not buy a Former Gremlin butchered with a Chevrolet Drive Train . Chevy Powered Mutt. Not another Butchered AMC with a Chevy Stuffed in it...... No reason for it since AMC has Interesting & Potent Parts Available - as well as a Racing History . ..........just a note - Welcome to an AMC - Powered Gremlin Club Bow Tie Boy regards. ..................bt. 1981 Eagle Kammback 6 Eagle Registry # 501 'Keep 'em Flyin' !
